METALLIC WINDOW-BLIND.

Specification of Letters Patent No. 20,576, dated June 15, 1858.

T o all whom it may concern:

Be it known that I, CHARLES NEER, of the city of Troy, in the county ofRensselaer and State of New York, have invented new and usefulImprovements in Metallic Vindow-Blinds; and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings and to the letters of reference markedthereon.

The object of my invention is to construct a rolling slat window blindframe, so that its parts may easily be dismembered for transportation orrepairs, at the angles of t-he frame by the use of joint bolts or screwsfor that purpose, and to so construct blinds as not to require anyfitting to the windows and the least possible mechanical skill to trimand hang, and also of rolling slats at small cost susceptible of beingeasily adjusted or that will remain at any desirable position.

To enable others to make and use my invention I proceed to describe itsconstruction.

The stiles are iron, cast nearly in the form of the letter T, as shownin a cross section Fig. (4). For five feet blinds the iron representedby either part of the letter T should be plump of an inch thick by 1,1,of an inch wide at or near either end rail and 1?,- inches in themiddle. That portion represented by the upright part of the letter Tbeing about of an inch from the center of the horizontal part so thatthe rolling tenon of a two inch slat being opposite or in line with thatpart of the stile represented by the upright part of .the same letterthere shall be sutilcient width on the face of the stile represented bythe horizontal part of the letter T into which the tenons enter to passa little beyond the width of the slat when h0rizon tal or in its widestposition.

The form of the stile may be seen by a cross section Fig. In Fig. (2) isshown a narrow Hat part (a a c a) in which are the holes for the slattenons and Atwo slight angles therefrom (b b) which are to prevent therubbing of the shoulders of the slats that they may be made to runclose. On the outside of each stile opposite the end of the rails thereis a small raise to give strength through which the joint bolts orscrews 4pass Fig. (5) (c c e). On the inside a small recess o r boxing(d ci d) `to receive the ends of the rails and at the ends, opposite thetop and bottom rails. They are widened out on the outside to form a linewith the center of the Stiles in order to give a good bearing to theends of the rails and to prevent injury of the slats or stilesthemselves by coming in contact with the side of the building Fig. e ee).

The holes for the tenons of the slats Fig. (4) should be about fg of aninch at the surface and lg of an inch at the bottom to render it easyentering the spring tenons and to construct them when brought downto theshoulder of the slatv for the purpose of easily adjusting the slats, theholes should be about it@ of an inch deep, and are all made by settingchills in the pattern it being drilled for that purpose as also theholes for the joint boltsor screws requiring no fitting for use. On eachhanging stile and on the raise Fig. (5) (g g) I cast a lug in connectionwith the raise forming the entire part of hinge usually screwed to theblinds, giving the necessary strength to that part -of the stile andsaving the expense of screws and the labor of putting them on. The topand bottom rails are in form similar to the stiles but are wider eachabout lf;- and 2 inches Fig. (7), the middle rail having the form of theletter H Fig. (6), all of them having a small rib or its equivalent forthe edges of the slats to shut against to close o' light and dust Fig.(71.]2. t 71,). The ends of the rails are filled up on the outside forabout of an inch of their length forming a shoulder to connect with thestiles yand .to receive the joint bolts passing through them inconnect-ing them with the rails Figs. (7 and 8) z' z' i).

That part of the hinge which is to be attached to the. building has avHat upright part through which the screws pass into the casing of thewindow frame with a flat horizontal part at right angles with theupright part Figs. (l0 and l1) with a small rib or brace in the cornerto give strength, on the horizontal part is an upright pivot( j)which ifvto be used on brick buildings should stand about l inches from thebackside of the part screwed to the window casing, and if a woodbuilding less. Around one side of this pivot on the plate is a sectionof a cylinder, on a radius from 1% to 2 inches and about of an inch highat its summit, that Abeing'level about l inch (7a) and descending overand upon the summit and these in-v clines run off but rests on oneincline when shut, and the opposite one when opento prevent alldisturbance by wind and requir- .ing much less to keep them in placethan if allowed to move or be at all loose when standing open or shutthe incline should be the greatest at the points where the blinds restwhen open or shut.

My slats are each formed of one entire piece of sheet iron or`othermetal with a hollow swaging from end t-o end at or near its center thereverse side ofthe hollow being a semi-circle and forming one side ofIeach tenon Fig. (9) O n each side of said hollow is a reverse hollow ofabout half the size The metal should be cut scant of an inch longer thanthe slat is to be from shoulder to shoulder it then being cut at eachshoulder from the edges to each side of that part forming the tenons (o)then the small parts being cut o far enough from the center to bendround and form a round tenon. Or one part may be left long enough to laparound the outside of the other and not being bent quite to touch thepart within forming a yielding part ,'or spring. But for the purpose ofadjustment of the slats in the blind more easily I cut the parts alittle short, and do not bring them to meet by about g of aninch'leaving them at their points a little out of a true circle withroom for them to yield, making a round rolling elastic hollow springtenon which will yield sufficiently to roll yet always retaining itsposition The edges of the slats are bent to close tight and givestrength Each slat has a small hole in one edge for the staples to therod Fig. (2)

The rod 1s made of a piece of sheet iron or other sheet metal about oneinch in width with the holes for the staples being made on a line in thecenter. It is then bent on a line with the holes bringing edges to aboutone eighth of an inch of each other it then being ready for use orshipment in attaching them to the slats a small wire staple is passedthrough the hole in each slat and through the holes in the rod and bentdown and the edges of the metal forming the rod press together and ifpreferred one edge of the metal may be wide enough to turn over theother forming a lock or small rivets may be used but Ido not considereither important.

I think it will be seen that by this form of stile that I get perhapsthe greatest strength of the iron and at the same time the necessary andmost desirable form to receive and protect the slats and stile itselffrom injury by coming in Contact with the wall of the building and ofmaking the slats to run close at the shoulders yet easily by means ofthe stiles being the fullest on a line with the tenons of the slats andfrom that point slightly beveled o toeach edge as seen by cross sectionFigs. (4:) (s) or in any form to drop a little below the line of theshoulders of the slats from near its center and by Fig. (3). It will beseen I get a good width to receive the slats and also a thin marginaround the entire blind,

adapting it to hangv upon the surface of the window casing by lappingmore or less as the size of the windows may vary dispensing with anyfitting, as shown by Fig. (t) to all the imperfections in the size ofwindow frames. They may lap one upon the other at theV center of thewindows Fig. ('2) the small openings at the top and bottom of one blindcaused by the lap of one on the other is provided for by a small rib onthe inside of top and bottom rail of the blind that laps upon the other.

By the form of the rails as seen by Figs. (6 and 7 it will be noticedthat the greatest care has been taken to get a strong and yet lightframe easily put together or dismembered. By the use of a hinge withdouble or reversing inclines over and upon which the weight of theblinds pass they may be held open as well as shut and avoid the use ofthe small delicate trimmings so liable to disorder and repairs. For verylarge blinds I would recommend setting the lower hinge down upon thewindow stool and have it sufficiently large to let the lower end of theblind itself run over and upon the inclines, rendering them more secure,and the inclines being a little more steep at each standing point,namely when the blinds are entirely open or entirely shut will renderthem sufficiently secure for any size.

By the above arrangements the consumer will get fire proof blinds hungon the building probably at as little cost as the common wood blind, atleast if the wood blinds are made as ornamental. All the expense oftting to the window and the principal part of trimming being dispensedwith requiring only screwing on of that part of the hinge which isalways attached to the building requiring very little skill, and as workis always done at less cost at the manufacturers and these blinds beingso constructed as to be easily and safely shipped to dealers, the publicwill derive the advantages.

What I claim as my invention and desire to secure by Letters Patentis- 1. Connecting the slats of metallic blinds by means of staplesinserted into a folded metallic strip, when bent up and securedsubstantially as specied.

2. I claim the circular spring tenon, formed on the ends of sheet metalblind slats substantially in the manner specied,

TM v

to be inserted into the hole in the stiles and cause the necessaryfriction, but prevent the tenon binding as set forth.

3. In combination with said sheet metal 5 blind slats I claim themetallic frames formed of the detachable rails and tapering Stiles inthe manner and for the purposes speciied.

4. I claim beveling the Stiles each Way from the line of holesreceiving,` the ends of 10 said metallic blinds slats, for the purposeof giving freedom to the slats when opened, but forming a tight jointWhen closed, as

set forth.
